HAIR DRYING APPARATUS Filed July 22. 1929 INVENTOR 005T 11/. PETERSON ATTORNEYS Patented Nov. 29, 1932 UNITED STATES PATENT OFFICE GUST W. PETERSON, LONG BEACH, CALIFORNIA, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, T0 WILLIAM H. H. DAVIS, OF SAN FRANCISCO, CALIFORNIA HAIR DRYING APPARATUS Application filed July 22,

My invention relates to apparatus for drying hair by means of jets or blasts of air, and more particularly to that type of apparatus constructed in the form of a hood to partly or completely envelope the head.

Drying apparatus of this type has the disadvantage of failing to remove sufficient moisture from the hair to maintainthe curl or wave therein for any protracted period of time, and for the reason that the construction of the apparatus is such that the jets of air emanating therefrom are not free to escape from between the scalp or the apparatus and hence considerable moisture s retained between the .twoso that the hair is not dried sufficiently to retain its curl or wave. Furthermore, previously designed driers of the hood type have no means of regulating the intensity of the air jets at any particular part of the hood, and consequently, where the hair at one part of the head is excessively moist it will not be dried to the same degree as the remainder of the hair, resulting in uneven and incomplete drying.

It is a purpose of my invention to provide a hair drying apparatus which supplies the deficiencies above recited, and in consequence effects rapid, uniform, and complete drying of the hair so that the curl or'wave is maintained therein for a protracted period.

I will describe only one form of hair drying apparatus embodying my -invent1on,'and will then point out the novel features thereof in claims.

In the accompanying drawing:

Fig. 1 is a view showing in front elevation one form of hair drying apparatus embodying my invention with portions of the dis- 40 tributing pipe and valves broken away to reveal the ports in the two.

Fig. 2 is a ver ical sectional view of the apparatus taken on the line 2-2 of Fig. 1.

Fig. 3 is a detail perspective view of one of the distributin pipes shown in Fig.1.

Fig. 4 is a detail perspective view of one of the valves embodied in the apparatus.

In carrying out my invention, I provide a hollow head H formed of metal or any other suitable material and having a round- 1929. Serial No. 380,049.

ed side 15 merging into a flat side 16.' Centrally of the rounded side is an opening defined by a collar 17 to which a hose 17 is adapted to be connected for conducting air under pressure to the head, it being understood that any suitable source of air pressure may be employed and as is customary in apparatus of this kind, the air is usually heated to effect a more rapid drying of the hair. At the flat side 16 of the head, a plurality of pipes P extend forwardly therefrom in an inverted U-shaped series, the several pipes being disposed at right angles to the side 16 and uniformly spaced one from the other. Each pipe at one end is secured to the head H soas to communicate with the interior of the head for the purpose of receiving air from the head for ultimate discharge from the pipe. Each pipe, as illustrated in Fig. 3 is provided with a series of ports 18 extending longitudinally thereof and uniformly spaced one from the other. Through these ports air is adapted to be discharged in the form of jets. and the intensity of these jets may be varied by the provision of a valve V contained in the pipe.

As shown in Fig. 1, the valve consists of a pipe or sleeve of a diameter to have a rotating fit within the pipe P, and this pipe is provided with a series of ports 19 exceeding in area those of the ports 18 by correspondingly spacing them so that by rotation of the valve the ports 19 may be brought into full or part registration with the ports 18. Once the valve is placed within the corresponding pipe, it is retained therein by bending the outer marginal end of the pipe inwardly to provide a lip 20, and to rotate the valve to control the emission of air from the ports 18 I provide a handle21 secured to the outer end of the valve as best illustrated in Fig. 1.

As will be clear from a consideration of Fig. 1 the ports 18 of the several pipes P are formed at the inner sides of the pipes so that the jets of air emitted therefrom are discharged inwardly against the hair when the apparatus is in applied position upon the head, and as indicated by the arrows, these jets project toa substantially common point within the apparatus. The intensity of the air jets from any one series of ports 18 may be controlled independently of the jets of the other series by rotation of the respective valve V so as to increase the intensity of the air emitted from any one pipe to increase the drying action in respect to the hair, and as the air jets emitted from all pipes are capable of being regulated, such increase in intensity may be effected at any required point about the head. As will be clear from the dash line illustration of a human head in Fig. 1 and 2, the apparatus is positioned on the head so that the hood is disposed at the rear of the head with the pipes P extending forwardly about the top and sides of the head, and as shown, the pipes preferably are graduated in length to extend only over the hair. With the apparatus thus applied, the air jets emitted from the pipes will be directed against the hair both at the top and sides of the head. i

For drying that portion of the hair at the rear of the head, I provide an additional distributing pipe P suitably secured in an open ing 22 in the side 16 of the head H adjacent the bottom thereof. The pipe P' is likewise provided with a series of ports 23 through which the passage of air from the interior of the head H is controlled by a tubular valve V having ports 24 therein. The valve V is rotatable by means of a rod 25 connected at one end to the valve and extending exteriorly of the head H where it is bent to form a handle 26. Thus by actuating the valve the intensity of the air jets emanat ing from the ports may be controlled as desired. It will be clear from a consideration of Fig. 2 the ports-23 are so positioned that the air jets emitted therefrom are directed .upwardly in the direction of the arrows so that when the apparatus is in applied position upon the head the air jets will impinge against the rear of the head and the intervening hair so as to effect drying of the latter.

Although I have herein shown and described only one form of hair drying apparatus embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

I claim:

1.
